  • AIoT Technologies and Applications for Smart Environments
  • Although some IoT systems are built for simple event control where a sensor signal triggers a corresponding reaction, many events are far more complex, requiring applications to interpret the event using analytical techniques to initiate proper actions. Artificial intelligence of things (AIoT) applies intelligence to the edge and gives devices the ability to understand the data, observe the environment around them, and decide what to do best with minimum human intervention. With the power of AI, AIoT devices are not just messengers feeding information to control centers. They have evolved into intelligent machines capable of performing self-driven analytics and acting independently. A smart environment uses technologies such as wearable devices, IoT, and mobile internet to dynamically access information, connect people, materials and institutions, and then actively manages and responds to the ecosystem's needs in an intelligent manner.

    In this edited book, the contributors present challenges, technologies, applications and future trends of AIoT in realizing smart and intelligent environments, including frameworks and methodologies for applying AIoT in monitoring devices and environments, tools and practices most applicable to product or service development to solve innovation problems, advanced and innovative techniques, and practical implementations to enhance future smart environment systems. Chapters cover a broad range of applications including smart cities, smart transportation and smart agriculture.

    This book is a valuable resource for industry and academic researchers, scientists, engineers and advanced students in the fields of ICTs and networking, IoT, AI and machine and deep learning, data science, sensing, robotics, automation and smart technologies and smart environments.

  • n-Type Crystalline Silicon Photovoltaics: Technology, applications and economics
  • Most solar cells currently in commercial use are p-type solar cells, due to their historically lower cost and ease of manufacture compared to n-type solar cells. However, due to improved manufacturing technology and falling cost in general, the cost difference between the two types has shrunk, making n-type solar cells an attractive option for future commercial high-efficiency solar cells.

    n-type solar cells are less prone to light-induced degradation, and are also less affected by iron impurities. This makes n-type solar cells more efficient compared to their p-type counterparts, with efficiencies of up to 25% being feasible in production.

    Challenges in the manufacturing process and regarding degradation still remain to be solved, in order to realise n-type solar cells' full potential. The challenges, solutions and opportunities afforded by n-type solar cells are explored in this volume.

    This book conveys current research and development for n-type solar cells and modules. With a systematic build-up, chapters cover the base material, wafer production, and the cell concepts including recent passivation techniques. Also covered are the related issues of solar module technology, such as encapsulation and interconnection, and degradation process management, including comparisons with p-type solar cells. In addition, economic and ecologic aspects and cost modelling are addressed.

    This thorough, concise reference is a valuable resource for researchers from industry and academia working in the field of photovoltaics.

  • Digital Technologies for Solar Photovoltaic Systems: From general to rural and remote installations
  • The rising share of photovoltaic (PV) energy requires sophisticated digital techniques for control, monitoring and integration with the grid. In remote areas, where no trained personnel might be nearby to intervene, such technologies are vital to ensure reliability and power quality, and to harness the solar potential of these locations. Moreover, tracking is necessary for moveable systems. Digital technologies can be used to enable and augment the use of PV energy in the grid, as well as for desalination, water pumping and hydrolysis.

    Digital Technologies for Solar Photovoltaic Systems: From general to rural and remote installations focuses on the latest research and developments in PV energy system operation and integration. It provides extensive coverage of R&D to overcome critical limitations to the use of remote PV systems.

    Chapters cover phase-shifting transformers, grid-connected PV micro-inverter, distribution automation, PV powered water pumping, maximum power point tracking and solar tracking, soiling effects and measurement, cleaning methods, IoT based PV module cooling and cleaning, control of energy storage, and energy management.

    This book is a highly useful reference guide for researchers, designers, operators, and experts involved with PV systems, as well as for graduate students.

  • Fundamentals of Inertial Navigation Systems and Aiding
  • The aim of this book is to provide an advanced introduction to inertial data processing (determination of attitude, velocity and position) along with design architectures and algorithms used to aid the inertial navigation system (INS). The emphasis is on the high-end sensors and systems used in aerospace applications (known as 'navigation grade' or 'nav grade').

    The subject of inertial navigation systems and how to aid them (reduce their inherent error drift) is complex and multi-disciplinary. Mathematics and physics along with electrical, mechanical and software engineering all are involved. This book has been written to serve as an introduction for students and those new to the field. Specialized topics such as rotation matrices, quaternions and relevant stochastic processes are covered in the book. The reader is expected to have a basic understanding of vectors, matrices and matrix multiplication as well as freshman-level differential and integral calculus.

    The basics of inertial position/velocity/attitude updating are first presented with respect to a conceptually simple inertially-fixed reference frame before the impact of the spheroidal rotating earth is covered. Similarly, the key concepts of the Kalman filter are first presented in the context of a scalar filter. Important aspects of the prediction error covariance and Kalman gain equations are thus covered in an intuitive sense before the full matrix formulations are described. By the end of the book, a thorough treatment of modern aided-INS architectures is provided.

  • Physical Layer Security for Wireless Sensing and Communication
  • Wireless physical layer (PHY) security has attracted much attention due to the broadcast nature of the wireless medium and its inherent vulnerability to eavesdropping, jamming, and interference.

    Physical Layer Security for Wireless Sensing and Communication covers both communication and sensing security from a broad perspective. The main emphasis is on PHY security, although other security measures are covered for the sake of completeness and as a step towards cross-layer security and cognitive security vision. After discussing the features of wireless channels from both the communication and sensing perspectives, the book details their exploitation for secure transmission utilizing various approaches. Wireless sensing and radio environment concepts are also addressed, along with the related security implications in terms of eavesdropping, disruption, manipulation, and, in general, the exploitation of wireless sensing by unauthorised users. Several solutions for these threats from the domains of wireless communication, military radars, and machine learning, are discussed.

    The book provides valuable information to researchers in academia and industry, as well as engineers, developers, and advanced students in the field of cybersecurity.

  • Cybersecurity in Transport Systems
  • The role of data and information and communication technology (ICT) is growing in all areas of transport, with autonomous vehicles among the most advanced examples. This opens up opportunities for malevolent interference, such as remote-control of vehicles for criminal or terrorist purposes or interruption of increasingly interconnected transport systems. It is therefore imperative that cybersecurity is upgraded and designed into new systems.

    Focusing on the management of security and the principles of security technologies in the context of transport systems, this book equips readers with an understanding of what management actions need to be taken and the sort of technologies available to defend against cyberattacks. To improve their decision making, managers need to understand how security practices and technologies work, so the book spans a range of areas: from regulations to security management, to the principles of selected technologies.

    Cybersecurity in Transport Systems provides insights across multiple modes of transport, including insight from seasoned practitioners. It also addresses advances and themes in current research and the future outlook as we move to increasing digital transformation.

    The book is aimed at managers in the transport sector but is widely applicable to other sectors, especially those that are safety critical. Much of the book will be useful to students considering careers in industries that rely on information technology, and to researchers in academia and industry.

  • Wind Turbine System Design. Volume 1: Nacelles, drivetrains and verification
  • Wind energy is a pillar of the strategy to mitigate greenhouse gas emissions and stave off catastrophic climate change, but the market is under tremendous pressure to reduce costs. This results in the need for optimising any new wind turbine to maximise the return on investment and keep the technology profitable and the sector thriving. Optimisation involves selecting the best component out of many, and then optimising the system as a whole. Key components are the nacelles and drive trains, and the verification of their work as a system.

    Wind Turbine System Design: Volume 1: Nacelles, drive trains and verification is a valuable reference for scientists, engineers and advanced students engaged in the design of wind turbines offering a systematic guide to these components. Chapters written by industry experts cover load calculation and validation, models and simulation, pitch and yaw system concepts and designs, drivetrain concepts and developments, gearboxes, hydraulic systems, lubrication, and validation. The book aims to enable readers to make informed and systematic choices in designing the best turbine for a given situation.

image of Non-Redundant Near-Field to Far-Field Transformation Techniques
  • Non-Redundant Near-Field to Far-Field Transformation Techniques
  • Near-field (NF) measurement techniques and the related NF to far-field (FF) transformations are gaining interest for their ability to allow an accurate evaluation of the radiation characteristics of those antennas whose electric sizes do not make it possible to perform direct FF measurements in a controlled and reflection-free environment, such as the anechoic chamber.

    This book provides a comprehensive treatment of classical NF-FF transformation techniques and describes the significant improvements achieved in their performance by correctly applying the non-redundant sampling representations of antenna radiated electromagnetic (EM) fields.

    Non-Redundant Near-Field to Far-Field Transformation Techniques is designed to meet the needs of students of antenna NF measurements, as well as of engineers and physicists working in the area. It has been written keeping in mind the fulfilment of two main objectives. The former is to provide all the analytical details on the derivation of the classical NF-FF transformation techniques without and with probe compensation, which are not easily available elsewhere in the literature. The latter is to give a comprehensive description of effective representations of the EM fields radiated over arbitrary rotational surfaces, which make use of a non-redundant (i.e., minimum) number of samples collected on these surfaces or along proper spirals wrapping them.
